20090254720 | SYSTEM FOR REBUILDING DISPERSED DATA - A digital data file storage system is disclosed in which original data files to be stored are dispersed using some form of information dispersal algorithm into a number of file “slices” or subsets in such a manner that the data in each file share is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other file shares. These file shares are stored on separate digital data storage devices as a way of increasing privacy and security. As dispersed file shares are being transferred to or stored on a grid of distributed storage locations, various grid resources may become non-operational or may operate below at a less than optimal level. When dispersed file shares are being written to a dispersed storage grid which not available, the grid clients designates the dispersed data shares that could not be written at that time on a Rebuild List. In addition when grid resources already storing dispersed data become non-available, a process within the dispersed storage grid designates the dispersed data shares that need to be recreated on the Rebuild List. At other points in time a separate process reads the set of Rebuild Lists used to create the corresponding dispersed data and stores that data on available grid resources. | 10-08-2009 |
20100023529 | METADATA MANAGEMENT SYSTEM FOR AN INFORMATION DISPERSED STORAGE SYSTEM - An apparatus includes a processing module and a network interface. The processing module is operably coupled to obtain; a data storage transaction request regarding a file; determine identity of a user based on the data storage transaction request; access file level metadata based on the identity of the user to determine a plurality of file slices associated with the file; access file slice metadata to identify at least one of a plurality of storage nodes that stores or is to store, a data slice and coded subsets of at least one of the plurality of file slices; and generate a data storage transaction message to facilitate a data storage transaction regarding the at least one of the plurality of file slices. The network interface is operably coupled to convert the data storage transaction message into a network data storage message and transmit it. | 01-28-2010 |
20100063911 | BILLING SYSTEM FOR INFORMATION DISPERSAL SYSTEM - An apparatus includes a processing module and a network interface. The processing module is operably coupled to: accessing user level metadata based on account identifier to identify a plurality of files associated with a user and retrieve user level metadata for the plurality of files; access file level metadata associated with the plurality of files to retrieve, for each of the plurality of files, file level metadata and determine, for each of the plurality of files, a plurality of file slices associated with a corresponding file of the plurality of files; and generate billing transaction information based on the user level metadata and the file level metadata of the plurality of files. The network interface is operably coupled to: convert the billing transaction information into a network billing transaction information message and transmit it. | 03-11-2010 |
20100161916 | METHOD AND APPARATUS FOR REBUILDING DATA IN A DISPERSED DATA STORAGE NETWORK - A method begins by identifying a data slice requiring rebuilding to produce an identified data slice, wherein the identified data slice is one of a plurality of data slices that constitute a data segment and wherein each of the plurality of data slices is assigned for storage by a corresponding one of a plurality of data slice servers. The method continues by retrieving at least m number of data slices from at least m number of the plurality of data slice servers, wherein m data slices of the plurality of data slices enable reconstruction of the data segment, and wherein the at least m number of data slices does not include the identified data slice. The method continues by reconstructing the identified data slice from the at least m number of data slices to produce a rebuilt data slice. The method continues by writing the rebuilt data slice to the corresponding one of the plurality of data slice servers or to a new slice server. | 06-24-2010 |
20100169391 | OBJECT INTERFACE TO A DISPERSED DATA STORAGE NETWORK - A data object interface to a dispersed data storage network is disclosed. The disclosed interface accepts read and write commands from a client computer and generates network commands that are forwarded to slice servers that form the storage component of the dispersed data storage network. The slice servers then fulfill the read and write commands. | 07-01-2010 |
20100217796 | INTEGRATED CLIENT FOR USE WITH A DISPERSED DATA STORAGE NETWORK - An integrated client computer for accessing a dispersed data storage network is disclosed. A client program operating on the client computer accepts commands from a user and in response, issues network messages to a plurality of slice servers implementing a dispersed data storage network. Data slices can be read, written or modified using the disclosed integrated client computer. | 08-26-2010 |
20100306578 | RANGE BASED REBUILDER FOR USE WITH A DISPERSED DATA STORAGE NETWORK - A message is generated by a computer operating on a dispersed data storage network indicating the inaccessibility of a plurality of data slices. A rebuilder application operates on the dispersed data storage grid and rebuilds inaccessible data slices, including those identified by the message. | 12-02-2010 |
